Installation
This section provides detailed procedures for properly
installing, configuring, and, as needed, troubleshooting
Kotron Model 822, 832 and 842 Sentinel Point Level
Switches.
1.1
Unpacking
Unpack the instrument carefully. Make sure all components have been removed from the packing material.
Check all the contents against the packing slip and report
any discrepancies to the factory.
Before proceeding with the installation, do the following:
• Inspect all components for damage. Report any damage
to the carrier within 24 hours.
• Make sure the nameplate model number agrees with the
packing slip and purchase order.
• Record the model and serial numbers for future
reference when ordering parts.
1.2
Electrostatic Discharge (ESD)
Handling Procedure
Magnetrol’s electronic instruments are manufactured to the
highest quality standards. These instruments use electronic
components that may be damaged by static electricity present in most work environments.
The following steps are recommended to reduce the risk of
component failure due to electrostatic discharge.
• Ship and store circuit boards in anti-static bags. If an antistatic bag is not available, wrap the board in aluminum
foil. Do not place boards on foam packing materials.
• Use a grounding wrist strap when installing and removing
circuit boards. A grounded workstation is recommended.
• Handle circuit boards only by the edges. Do not touch
components or connector pins.
• Make sure that all electrical connections are completely
made and none are partial or floating. Ground all
equipment to a good, earth ground.

1.3
Before You Begin
1.3.1 Site Preparation
Each Kotron Model 822, 832 and 842 switch is built to
match the specific physical specifications of the required
installation. Make sure the probe connection is correct for
the threaded or flanged mounting on the vessel or tank
where the switch will be placed. See Section 1.4, Mounting.
Make sure that the wiring between the power supply and
the Model 822, 832 or 842 switch is complete and
correct for the type of installation. See Section 3.2,
Specifications.
When installing the Model 822, 832 or 842 switch in a
general purpose or hazardous area, all local, state, and
federal regulations and guidelines must be observed. See
Section 1.7, Wiring.
1.3.2 Equipment and Tools
No special equipment or tools are required to install
the Model 822, 832 or 842 switch. The following items
are recommended:
• 11⁄8" open-end wrench or adjustable wrench to fit the
probe process connection size and type.
• Flat-blade screwdriver
1.3.3 Operational Considerations
The Model 822, 832 or 842 switch should be located for
easy access for service, configuration, and monitoring.
There should be sufficient headroom to allow the probe
to be inserted into the tank. Special precautions should
be made to prevent exposure to corrosive atmosphere,
excessive vibration, shock, or physical damage.
The electronics should not be exposed to ambient temperatures above +160° F (+70° C) or below -40° F (-40° C).
The proper operating temperature range for the display is
-4° F (-20° C) to +160° F (+70° C). The temperature
limits for the probe depend on the style and part number
of the specific probe used.

1.4
Mounting
The Model 822, 832 or 842 switch can be mounted to
a tank using a variety of process connections. Generally,
either a threaded or flanged connection is used. For information about the sizes and types of connections available,
see Probe Brochure 50-125.
Make sure all mounting connections are properly in place
on the tank before installing the probe. Make sure the
Kotron probe is correct for the intended installation.
It is common practice to use the metal tank wall as the
reference electrode. In such cases, it is required that the
probe housing makes a good electrical connection to the
tank wall. If there is any doubt about this connection or
to the use of PTFE thread tape gaskets, paint, rust, or any
other reason, a separate strap should be installed between
the probe housing and the tank.
Caution: This unit contains CMOS electronics which may be
damaged by static electricity. Do not touch any semiconductor devices unless you are properly grounded.
Caution: When a probe is used in an abrasive medium, inspect the
probe periodically for visible surface wear. If damage to
the probe insulation is found, replace the probe.
Metal Walled Tanks
On water-based liquids, there should be no problem with
sensitivity or linearity. With non-conductive, low dielectric
media, sensitivity can be enhanced by locating the probe
close to and parallel with the tank wall. If this is not practical, a ground reference probe may be the solution.
Non-Metallic and Glass-Lined Tanks
With plastic, concrete, wood, or any other non-conductive
walled vessels a ground reference is required. Most commonly, this electrode will be in the form of a concentric
ground tube (i.e., stilling well). In questionable circumstances, consult the factory. In all cases, a good electrical
connection must be made between the ground surface and
the probe housing.
Switch/Probe Assembly
Switches with probes up to and including 12 inches
(300 mm) in length are shipped pre-assembled. All other
switches are shipped unassembled to avoid damage during
transit. These transmitters must be assembled prior to
mounting. Choose your particular configuration from the
following sections and follow the instructions carefully.

Recommended Mounting with Nozzle
Figure 3
Not recommended
Figure 4
Recommended Horizontal Mounting
Horizontally mounted probes provide a high degree of sensitivity for use with non-conductive liquids as only approximately 0.5 inches (12 mm) of level change is required to
completely cover (or uncover) the probe.
Horizontally mounted probes should be installed so that
the probe is parallel to and at the level at which the
control point is desired. Refer to Figure 1.
Avoid any installation method in which the material may
become trapped in the mounting nozzle, thus preventing
the probe from signaling when the level recedes. Refer to
Figures 2 and 3.
NOTE: If nozzle mounting is unavoidable, the probe must be installed
with an inactive metal sheath having a length of at least 1 inch
(25 mm) greater than length of the nozzle. A sheath is required
to render the length of the probe within nozzle insensitive to
capacitance change. Refer to Figure 2.
Guarded Probe
Unit will signal at probe level. Refer to Figures 4 and 5.
NOTE: The guard element must be located outside of the nozzle.
Do not horizontally mount the unit in a nozzle deeper than
3 inches (75 mm). Refer to Figure 5. The medium may buildup
in the nozzle and cause false activation.
Alternate Horizontal Mounting
On applications involving viscous liquids or materials
which tend to cling or buildup, horizontally mounted
probes should be installed at a slight downward angle to
allow material to drain from probe rod. With this type of
installation, the packing gland face of probe assembly
should extend into the tank (or vessel). Refer to Figure 6.
1.4.2 Vertical Mounting
Figure 5
Recommended Horizontal Mounting
Vertically mounted probes provide the capability to adjust
the control point up or down a section of probe rod by
means of calibration adjustments within the unit.
Vertically mounted probes should be installed so that the
end of the probe rod is at least 2 inches (50 mm) below
the lowest desired level control point with conductive
materials or 4 inches (100 mm) below the lowest desired
level control point with non-conductive materials. Refer to
Figure 7 on page 5.

Calibration
2.1
Operator Set Up
MagneCal™, the Sentinel’s sophisticated calibration software,
uses a microprocessor-based user interface, which provides
the operator unmatched flexibility and programmability
for a variety of level control applications. These features are
built into the controller and are entered via three tactilearrow, DOWN
arrow, and
feedback keys (UP
ENT
) located on the amplifier circuit board. In addition, a 4-digit LED displays the operating parameters and
values. The keys and their functions are shown below.
ENT
Upon power up, the LED will display the following message: Magnetrol Int’l followed by a series of walking M’s (multi-point) or S’s (single point), based on the
calibration configuration selected. This is the normal
RUN mode.
UP/RAISE: Use to scroll up through menu selections, or
raise numeric values. There are three speeds for scrolling
numeric values. Ramp speed is increased by continuously
arrow key. To decrease speed as the
depressing the UP
arrow key
desired value is approached, release the UP
and unit will revert to the slowest ramp speed.
DOWN/LOWER: Use to scroll down through menu selections or lower numeric values. There are three speeds for
scrolling numeric values. Ramp speed is increased by
arrow key. To
continuously depressing the DOWN
decrease speed as the desired value is approached, release
arrow key and the unit will revert to
the DOWN
slowest ramp speed.
ENT
ENTER: Use to select displayed value and to continue to
the next menu selection. Complete menu layouts are
provided to show the user-selectable parameters.
NOTE: The unit will automatically time out and revert to the RUN mode
after 60 seconds of no key strokes. Any information already
entered is secure, and the calibration may be safely resumed
at any time.

The microprocessor-based Sentinel offers all operator functions and setup procedures from the three tactile-feedback
keys described above. Due to the number of user programmable features included in the unit, the calibration flow
chart is extensive. The flow chart is modular, however, it
can be divided into five subsections or program paths
which are connected to a home base, or normal operating
mode, RUN (walking M or S). When letters scroll horizontally across the LED and no error messages are displayed,
all systems are functioning properly. The calibration flow
chart structure is shown on page 12.
NOTE: If MagneCal precalibration data was entered at the
factory, use Advanced Calibration procedures (Section 2.5) in
conjunction with the standard calibration procedures.

Calibration—Single Point
2.3.1 Program Path 1 — Configuration
The SING (single point) program is for single point alarm
applications and allows for proper calibration without level
change. The MULT (multi-point) program is for all pump
(wide differential) control, multiple relay applications,
and single point applications where an adjustable set point
is needed.
NOTE: Specific order of the configuration modes must be followed for
proper calibration of the Sentinel Level Switch. It is imperative
that the user select CONFIGURATION for the first calibration
procedure. Within the CONFIGURATION mode, the single or
multi-point operation must be selected. This selection affects
the balance of the configuration procedures and will signifiRUN
cantly affect the performance of the level switch if the modes
of operation are not followed.

medium in the vessel, reestablish PRHI point (for best
results at least 25% of the probe should be immersed).
Relay control parameters are now calibrated to the new
process medium.

Not applicable
Not Applicable.
Preamplifier Test
Integral: consult factory.
Remote: measure current on the positive
(+) side of circuit, between preamplifier and
main amplifier; 30 to 40 mA is proper.
Probe Short Test
Disconnect the probe wire from the probe.
Measure the resistance between the probe
connection screw and the metal probe
mounting nut; use the highest resistance
scale available. A reading of 10 megohm
or greater (and stable) is proper.
Error Message 11 (ER11)
Error Message 12 (ER12)
NOTE: If the application is an insulated probe in
a conductive medium, it helps to have the process
level at the highest point possible. This aids in
checking for nick or cuts in the probe insulation.
Error Message 13 (ER13)
Open probe circuit
Check wiring between electronics and
probe.
Error Message 16 (ER16)
Immeasurable signal – No wave form
beyond maximum capacitance
capability.
Integral: Consult factory.
Remote: Perform checks described
under Error Messages 11, 12, and 13.

Service Policy
Return Material Procedure
Owners of Magnetrol controls may request the return of a
control or any part of a control for complete rebuilding or
replacement. They will be rebuilt or replaced promptly.
Controls returned under our service policy must be
returned by Prepaid transportation. Magnetrol will repair
or replace the control at no cost to the purchaser (or owner)
other than transportation if:
So that we may efficiently process any materials that are
returned, it is essential that a “Return Material
Authorization” (RMA) number be obtained from the
factory, prior to the material's return. This is available
through Magnetrol’s local representative or by contacting
the factory. Please supply the following information:
1. Returned within the warranty period; and
2. The factory inspection finds the cause of the claim to
be covered under the warranty.
If the trouble is the result of conditions beyond our control; or, is NOT covered by the warranty, there will be
charges for labor and the parts required to rebuild or
replace the equipment.
In some cases it may be expedient to ship replacement
parts; or, in extreme cases a complete new control, to
replace the original equipment before it is returned. If this
is desired, notify the factory of both the model and serial
numbers of the control to be replaced. In such cases, credit
for the materials returned will be determined on the basis
of the applicability of our warranty.
No claims for misapplication, labor, direct or consequential damage will be allowed.

returned to the factory.
A Material Safety Data Sheet (MSDS) must accompany
material that was used in any media.
All shipments returned to the factory must be by prepaid
transportation.
All replacements will be shipped F.O.B. factory.
